For any of the following that can exist as isomers, state the type of isomerism and draw the structures:
(a) [Zn(en)F2]
(b) [Zn(H2O)(NH3)FCl]
(c) [Pd(CN)2(OH)2]2-
Short Answer
Expert verified
The 2 chemical structures given into the questions show isomerism. They exist as geometric (cis-trans) isomers and optical isomers while one structure doesn’t show any kind of isomerism.
- [Zn(en)F2] -Optical isomerism
- [Zn(H2O)(NH3)FCl] - No isomerism
- [Pd(CN)2(OH)2]2-- geometric (cis-trans) isomerism
Step by step solution
01
Concept Used – Isomerism
Definition of different kinds of isomers
- Constitutional (structural) isomers - same formula, differently connected atoms; they can occur in two types:
- Coordination isomers - they occur when the structure of the whole compound is the same, but the structure of complex ion is different
- Linkage isomers - they occur when the structure of the complex ion is the same, but the donor atom which ligand uses is different
- Stereoisomers - they have the same connections between atoms, but the atoms have different spatial arrangements; they occur in two types:
- Geometric (cis-trans) isomers - different spatial arrangements of atoms or groups, relative to the central metal ion.
- Optical isomers - they occur when molecule cannot be superimposed with its mirror image.
